Piston Slap: Portal Protection for an Erratic Winter?

TTAC Commentator Arthur Dailey writes:

Sajeev,

As I look outside a the terrible weather, I felt it was opportune to ask you (and the B&B) a relatively simple yet timely question about preventing car door freezing: door handles, windows, etc, during the freeze and thaw cycles that we are increasingly experiencing.

On Sunday our temperature reached a record low of – 22C but on Thursday we had driving rain and a record high of + 10C melting all the snow. Friday we are dropping to – 13C with high winds and freezing rain/sleet/snow. All of these freeze thaw cycles play havoc with our autos.

The high temperatures combined with the salt used to keep the roads less icy results in rusting. Perhaps less serious but just as frustrating are the freezing of windows, doors, door locks and door handles.

Vellum Venom Vignette: Of Portal Handling Pleasures

Hi Sajeev,

G’day from Down Under. Big fan of the Vellum Venom column of yours. Car design, and more importantly the smaller details of car design have always fascinated me, even though I couldn’t design a car if my life depended on it. The first bit of design that really hit me was the first appearance of BMW’s “Angel Eyes” on the E39 M5.

Anyway, I’ve always wondered when and more importantly why have the “pull-type” door handles become the norm?

  • Michael Smith I drive 100-300 miles a day in new BMWs, Mercedes-Benzes, and GM SUVs. Some are already equipped with automatic braking.It's the first thing I turn off when I start the car.I've had experiences where (as the author notes) the system gave false alarms and stabbed the brake pedal, threatening my ability to control the car.Further, every driver encounters situations where, for example, legal following distance must be momentarily compromised in order to avoid a difficult situation. When the system intervenes, it disrupts the driver's plan of action. This can lead to a collision as the driver has to suddenly react not to his surroundings, but to the system.Not only is automatic braking an insult to skilled drivers, it's dangerous to everyone.

  • Dave M. My hipster daughter is greatly into it. We watched the race together this weekend. It was interesting but I'm not devoted to it like she is. She'll be at the Austin race in October.

  • Steve Biro There are 24 races on this year’s F1 schedule. And I guarantee you no more than two will be reasonably exciting, Meanwhile, F1’s reception for Andretti reveals the dark underbelly of the sport. I have followed F1 since the 1960s and, frankly, I am running out of interest. I’ll catch a race if it’s convenient but won’t bother DVRing them.
